Albedo is defined as
\[
\boxed{
\text{Albedo}
=
\frac{\text{Reflected Solar Radiation}}
{\text{Incoming Solar Radiation}}
}
\]
Higher albedo means greater reflection.
Albedo is the fraction of incoming solar radiation that is reflected back into space by a surface.
A surface with high albedo reflects more sunlight, whereas a low-albedo surface absorbs more energy.
Hence,
\[
\boxed{\text{Reflection}}
\]
is the correct answer.
Therefore,
\[
\boxed{(B)}
\]
